Were the greek goddess hemera live?

Hesiod, Theogony 744 ff :

"[At the ends of the earth, where lie the roots of earth, sea, Tartaros :] There stands the awful home of murky Nyx wrapped in dark clouds. In front of it [Atlas] the son of Iapetos stands immovably upholding the wide heaven upon his head and unwearying hands, where Nyx and Hemera draw near and greet one another as they pass the great threshold of bronze: and while the one is about to go down into the house, the other comes out at the door. And the house never holds them both within; but always one is without the house passing over the earth, while the other stays at home and waits until the time for her journeying come; and the one holds all-seeing light (phaos) for them on earth."
